International sporting event
Shooting – Women's 25 metre pistol at the 2015 Pan American Games
The event consisted of two rounds: a qualifier and a final. In the qualifier, each shooter fired 60 shots with a pistol at 25 metres distance. Scores for each shot were in increments of 1, with a maximum score of 10. The first 30 shots were in the precision stage, with series of 5 shots being shot within 5 minutes. The second set of 30 shots gave shooters 3 seconds to take each shot.
The top 8 shooters in the qualifying round moved on to the final round. There, they fired an additional 20 shots. These shots scored in increments of .1, with a maximum score of 10.9. They were fired in four sets of 5 rapid fire shots. The total score from all 80 shots was used to determine final ranking.
The winners of all fifteen events, along with the runner up in the men's air rifle, skeet, trap and both women's rifle events will qualify for the 2016 Summer Olympics in Rio de Janeiro, Brazil (granted the athlete has not yet earned a quota for their country).
